CLOTHES-W'RING-ER.

Specification of Letters Patent.

Application filed May 4;, 1916. Serial No. 95,4:73.

and Frrzrruon C. SPEER, citizens of the United States, residing at New York city s and Madison, respectively, in the counties of New York and Morris and States ofNew York and New Jersey, have invented certain new and useful improvements in Clothes- Wringers, of which the following is a speci- 11o fication, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in clothes wringers,

and more particularly to pressure releasing 16 means for the pressure rolls thereof, the obj ect being to provide means for releasing the pressure on the pressure rolls by releasing the top bar of the wringer frame so as to allow the same to move vertically. Another object of our invention is to pro vide a wringer in which a removable top bar is employed carrying a bowed spring having substantially key-hole shaped slots in the ends thereof cooperating with headed studs so asto hold the top bar in position within the wringer frame in such a manner that when the spring is elongated the top bar will be released so as to allow the pressure screws carried thereby to be moved out of contact with the pressure means for the pressure rolls. c

Other and further objects and advantages {of the invention will be hereinafter set forth and the novel features thereof defined by the floyappended claims.

In the drawings, Figure 1 is a side elevation of a wringer partly in section showing the application of our improved construction of pressure releasing means. Fig. 2 is .a top plan view of a wringer provided with our improved construction of pressure releasing means. Fig. 3 is a detail end elevation. Fig. 4c is a detail perspective view of the end portion of the-spring arid the headed 4 stud, and Fig. 5 is a detail perspective viev. of a slightly modified form of spring and headed stud.

Like numerals of reference refer to like parts in theseveral figures of the drawing. In the drawing; 1 and 2 indicate a pair of slotted side bars connected together adjacent their'lower ends by cross bars 3 forming a. wringer frame of the ordinary construction. Slidably mounted Within. the slotted POT? tions of the side bars are superposed bearings 4 and 5 in which are mounted shafts 6 and 7 carrying coiiperating pressure rolls 8 and 9 one of said shafts being provided with means for driving the same, not shown. The shafts 6 and 7 are provided with meshing gears, not shown, inclosed by gear casings.

i0 in order to protect the clothes from being caught in the gears in passing between the pressure rolls. I

slid-ably mounted within the slotted portions of the side bars 1 and 2 is a cross bar 11 the ends of which are arranged on top of the upper bearings 5 and upon which the free ends of a pressure spring 12 are mounted so as to exert a pressure on the pressure rolls. The pressure spring 12 is" carried by a pressure bar 13, the ends of which are slidably mounted within the slotted portions of the side bars 1 and 2 of the ringer frame, said pressure her being provided with beau ing plates Lt adjacent the ends thereof for the purpose hereinafter fully described.

Loosely mounted within the upper ends of the slotted portions of the side bars 1. and 2 is a top bar 15 adapted to slide within the slotted portions of the side bars so as to move vertically therein, said t p bar being Patented Nov 2%., 191%. r

provided w th threaded boxes l6 adjacent its ends in which are mounted the threaded portions, of pressure screws ll" which engage the bearing plates 14 ofthe pressure bar 13 so as to adjust the pressure on the pressure rolls.

Arranged on the outer faces of the side bars 1 and 2 adjacent their upper ends are members 18 which are provided with ofiset upwardly extending headed studs 19, the heads QOthereof being conical in shape ha in g rounded base portions 21 in order to pro duce a head of acorn shape for the purpose hereinafter fully described.

Mounted on the top bar 15 is a bowed spring 22 provided with slots 23 through which the pressure screws 17 pass and upon which the bowed spring 22 is slidably mounted so that the endsjthereof can expand and contract in respect to the screws. By mounting the bowed spring 22 on the top bar 15 in this manner, the pressure screws 17 hold the bowed spring in position thereon in such a.1nanner that the same is free to move in respect to the top bar for the purpose hereinafter fully described. The bowed spring 22 is provided with substantially horizontally disposed end portions having substantially key-hole shaped slots 24 formed therein through which the headed studs 19 are adapted to pass and be interlocked so as to hold the top bar rigidly in position With the side bars of the wringer frame in order that the pressure screws carried thereby can exert the desired pressure on the pressure means.

When the bowed spring is in the position as shown in Fig. l, the reduced portions of the key-hole slot 24 are under the heads 20 of the headed studs 19 so as to prevent the top bar 15 from moving vertically within the wringer frame, and if a foreign object is drawn between the pressure rolls of the wringer, it is only necessary for the operator to strike the bowed spring to elongate the same which will throw the ends thereof outwardly so as to bring the enlarged portions of the key-hole slots in alinement with the headed studs so as to allow the studs to pass through the key-hole slots and release the top bar.

In the modification shown in Fig. 5, we provide-a bowed spring 25 for holding the .top bar in position with a slot 26 having a reduced portion adapted to extend under the spherical head 27 on a'stud 28 carried by the wringer frame, and While the slot 26 is substantially key-holed in shape, the edges are cut away so that the rounded portion converges into the reduced portion -in such a manner that the-headed stud when arranged over the reduced portion will hold the spring in position to retain the top bar in position within the wringer frame, and when brought into alinement with the .enlarged portion of the slot will pass through the same so as to release the top bar.

From the foregoingdescription, it will be seen that we have provided a clothes wringer in which the top bar carrying the pressure screws is held in position by a bowed spring having substantially V-shaped slots formed in the ends thereof coeperating with the headed studs in such a manner that when the headed studs are arranged over the reduced portions of the slots. the top bar is normally held in position within the wringer frame and when the enlarged portions of the slots of the spring are forced in alinement with the headed studs, the top bar is released so as to instantaneously release the pressure on the pressure rolls.
